An amorphous potassium aluminosilicate filtration media which may be mixed with activated carbon filters water to remove oxygen, chlorines, hardness, alkalinity, ammonia, hydrogen, hydrogen sulfide, sodium sulfite and other contaminants. The particular sodium aluminosilicate is a porous amorphous material formed under ultraviolet light or sunlight to produce pore sizes of 60 .ANG. to 250 .ANG. at ambient temperatures (20.degree. C.-35.degree. C.) and low relative humidity (5%-20%). The media is initially formed as a microporous primarily amorphous gel containing Na.sub.2 O, Al.sub.2 O.sub.3, SiO.sub.2 and H.sub.2 O. The sodium therein is displaced by potassium, whereby the filter removes impurities from water without introducing sodium. The potassium aluminosilicate may be a second stage filter to a first stage filter composed of a strong base anion media charged with potassium carbonate and/or bicarbonate. The filtration media may be used in any type gravity filter including that in an inverted bottle type dispenser for filtering water the flowing from the bottle to the spigot and also filtering air which bubbles back into the bottle in response to opening the spigot. The media as blended with activated carbon may be composed of molded particles having diameters from 1 to 100 microns and preferably 1-20 microns with an average diameter of about 10 microns. It also may be blended with zirconium oxide without carbon for reducing anion and cation species from drinking water.

[ Having thus disclosed my invention, what I claim as new and desire to secure by Letters Patent of the United States is:] [1.]1. An adsorbent material comprising a synthetic potassium aluminosilicate composed at least in part of porous non-crystalline material that was subjected to ultraviolet radiation during its formation of its said porous non-crystalline structure to produce pores in said material which have diameters between about 60 Angstroms and about 250 Angstroms. [7.]7. A process for the filtration of potable water which comprises flowing said water through a filter composed of synthetic potassium aluminosilicate media which removes oxygen from said water, wherein said potassium aluminosilicate media was subjected to ultraviolet radiation during its formation resulting in a non-crystalline structure and having pores, the diameters of said pores being at least about 60 Angstrom units. [56.]56. In the process of carbonating water, the improvement comprising: filtering the water with a synthetic, non-crystalline potassium aluminosilicate filter material having pores of at least about 60 Angstrom prior to carbonating the water, said pores having been formed by exposing said media to ultraviolet radiation during formation.
